Abstract
A digital camera comprises a solid state imaging device provided with an optical low-pass filter. A photographing optical system forms an object image on a light receiving surface of a CCD through the optical low-pass filter. An electronic-charge accumulation-time control program is stored in a ROM of a system control circuit to determine optimum exposure parameters according to which a photography is performed. The electronic-charge accumulation-time control program has a program diagram showing a relationship between an electronic-charge accumulation-time and an aperture value and/or an ISO speed.
